13 Claims. (Cl.155-180) It is an object of this invention to f provide'an upholstered chair of greater comfort than heref tofore possible. w

VA further object is to decrease the; laborv required in the manufactureof such furnituref Another object is to'facilitate the repairs 'ofupholstered furniture. f f Y It is also an object of the instantinvent-ion to'reduce the cost of distributionof furniture. YAnadditional object is to increase the useful life of upholsteredfurniture.

Other objects of the instant` invention will become apparent in thecourse V- of the following specification. Y

In the accomplishment of these objectives, the inside of the arms of anychair frame designed to be upholstered are first formed and the insidecover of the arms attached as well as the outer covers of the arms andback. In the framework `of the back, a removable back member is'insertedwhile in the framework of the seat, a removable seat member is inserted.vThe removable members are unique in thelmethod off attaching fthecovers and related members. HRather'thanusing the` well known webbingtackedalong the edges of theback and seat frameworks; theremovable backand seat members are made Withindividual frames designed to be tted intocorresponding positions of the chair. Along the base of the separateframes are protuberances which,Y after the burlap and iillingl and coverare in position over thesprings, are designed to be bent over the edgesof the burlap and cover holding thev same nsecurely in place and makingeach oftheY members ifconnection with the accompanying drawing showing,by way of example, a preferred embodiment of the inventive idea.

Referring now in greater detail to the drawings in which like referencenumerals indicatelike parts, reference numeral I0 (Figs. 1 and 2)indicates the upholstered chair, I I the removable back member, and I2the removable seat member..

The chair I0 is constituted of the upholstered arms I3 and I4 (Fig. 1),the back framework I5 (Fig. 2), and the seat framework 16.

The upholstered arms I3 and I4 are formed in the usual manner.

The back framework I5 is made with the spaced parallel side members I'Iand I8 (Figs. 1 and 2), and the spaced parallel top member I9 (Fig. 2)and bottom member 20 which may be joined along corresponding ends in theusual manner. Within the back framework I5 are the second members 2| and22 (Figs. 1 and 7) Vspaced parallel to the side members I'I and I 8,extending between the top and bottom members I9 and 20 and substantiallyin the line of intersection of the plane of the insidesurface portionsofthe arms I3 and I4 extended with the back framework I5. Of course, thepositioning of the second members may be varied as desired and even thedesign 'of the back framework could bechanged. The back framework I5 isattached tothe seat sharp edge from excessive wear on the subse-vquently described burlap and cover.A long `the bottom of the non-turnedportion-of the angle bars is a row of tooth-like protuberances 24.

in a known manner to maintain the same in a proper position.

The seat framework I6 (Fig. 2) is made with the spaced parallel sidemembers 45 and 46 (Fig. 6), and the front member 41 spaced parallel tothe back member 48, said members being secured along corresponding endsin a known manner.

Within the seat framework I 6 is the removable seat unit I2 also formedof the angle bars previously described and constituted of the opposedside members 49 and 50, the front member 5I in opposed relationship tothe back member 52.

, l'I-'he length of the members 49, 50, 5I, and 52 is which may beformed integral withthe body pori tion by stamping or otherwise.v'Ihe-protuberserted through the burlap and cover and then turnedthereover. One protuberance 24 may be seen in Figure in the unbentposition and two in the bent position after having been passed throughthe burlap and cover. Y

The angle bars are formed into1 a frame for the removable back member(Fig. '7) in which there is an upper rectangular portion 25 vand a lowerrectangular portion 26 separated by the common member 21. The upperrectangular portion 25 is formed with the opposed end members 28 and 29,the top member 30, the common member 21 elongated by the end members 3land 32 and spaced parallel to the top member 30. While the positioningof the common member 21 and associated end members 3I and 32 in theframe may be varied, it has been found desirable to havethe samesubstantially along the line of intersection of the plane of the topsurface portions of the arms I3 and I4 extended with the back frameworkI5. The common member 21 need not necessarily be an angle bar but theend extensions 3| and 32 are and carry along the bottom surface portionsthereof the previously mentioned protuberances '24. The various membersare fastened along corresponding ends by any suitable means.

The lower rectangular portion 26 is made with the common member 21 andthe bottom member 33 spaced parallel thereto and the spaced parallel endmembers 34 and 35 which are secured along correspondingends in a knownmanner. Y

The top member of the upper rectangular portion 25 is releasablyattached tothe top member of the back framework I9 by the catches 36,31, and 38 which are illustrated in Figure 4. In this gure it will benoted that the nonturned portion of the angle bar with the burlap andcover secured by the protuberances 24 is releasably slid between thecatch and the outside surface portion of the top` member IE).y Somewhatsimilar catches 39 vand 49 are disposed onthe second members 2i and 22for the releasable support of the common member 21. As shown in Figure7, the spaced parallel side members 28 and 29 ofthe upper rectangularportion 25 are supported by the upper part of the spaced parallel sidemembers I1 and I8 of the back framework I5 while the spaced parallelside members 34 and 35 of the lower rectangular portion 2G are supportedby the lower part of the second members 2| and 22 of the back frameworkI5. Intermediate the spaced parallel side members of the removable frameare the spaced parallel supports 4 I, 42, and 43 upon which the knownspring members 44 are mounted in a kno-wn mannen The spring members 44may be fastened together at the top :less thanthe length of thecorresponding members of the seat framework so that the removable seatcan be substantially inserted therein. The

various members are attached as desired along corresponding ends and theside members 49 and 50 flare upwardly and outwardly at the front as bestseen in Figures Zand 9 to compensate for the variation in elevation ofthe upper edge of the front member 41 compared with the points ofattachment 53a (Fig. 2) along the back of the seat framework I6 (Fig.2). Along the front member 5I of the frame of the seat unit I6 are thesimilar key openings 53 which are removably attached over the screws 54as shown in Figure 10. Within the frame of the seat unit I6 are thespaced parallel spring supports 55, 56, 51, and 58, similar to thepreviously described spring supports 4 I, 42, and 43 for the removableback member II, which support the springs 59 interconnected in the planeof the top portions thereof in any known manner. Spring members 60support the sides of the frame within the seat framework as shown. Inaddition, suspension springs 6I (Fig. 2) under tension are connectedbetween the bottom member 33 of the removable back member and theremovable back member 52 of the removable seat unit I2 as shown inFigures 2 and 6.

The operation is as follows:

A chair frame is first made in the usual manner. The removable back andseat members with the springs attached or otherwise are then made by thespring manufacturer ready for the filling and covers which are attachedby virtue of the protuberances 24 eliminating the use of tacks andwebbing. Manufactured paddings as now supplied are ideal for this methodof manufacture and there is no need for special or extra reinforcementsor frames as now required for some types of springs. The tops of thesprings may be secured in the usual manner after which the burlap member62 (Fig. 5) and the cover 63 are inserted with the filling therebetweenas desired and the edges of the burlap 62 and cover 63 inserted over theopen protuberances 24 which are then bent overv the outside surfaceportion of the cover as shown in Figure 5. The removable back member IIis then inserted in the back framework with the fiat surface portion ofthe angle bar forming the spaced parallel top member 30 inserted in thecatches 36, 31, and 38, and the common member 21 in the catches 39 and40. To hold the back member II down tightly onthe catches, one or moresprings 6I (Fig. 2) are connected between the bottom of the removableback member II and the back of the removable seat member I 2. Theremovable seat member I2 is next inserted with the key openings 53 inthe spaced parallel front member 5I over the screws 54 after which thesprings 60 are attached between corresponding side and back members ofthe seat frame work and removable unit as shown.

By this arrangement, sagging bottoms are eliminated, extra spring actiongiven the seat for added comfort, and the life of the seat membersubstantially increased. Moreover, by this arrangement, show room spaceis saved because one chair can be equipped with different removable backand seat members the better to sho-w how the chair will look withdifferent treatments. If and when the removable back and sea't membersneed repair, the work may be accomplished without removing the chairfrom the premises. If when making repairs, the protuberances 24 arelost, the sleeve 62a (Fig. l2), is slipped over the base portion of theangle bar to supply new protuberances 24.

Of course, a rubber top may be used in place of the springs and llingand the support bars for the springs or rubber may be run in twodirections (not shown) and laced or riveted where crossed.

It is apparent that the specific illustrations shown above have beengiven by way of illustration and not by way of limitation and that thestructures shown above are subject to wide variation and modificationwithout departing from the scope or intent of the present invention. Allof such variations and modifications are to be included Within the scopeof the present invention.
